To all `'whom/,itfmwqz/ concern: .Be it 1known Lthat I, JOHN Balearen vacitizen yof "theUnited States, residing at;

stood by those skilled the .art the light vof the followingdescriptionof vthe construction shown in the accompanying drawings as mypreferred embodiment.

An object of .my invention is .to produce an exceedingly sim le,economical and yet strong and ,durab e -tank lug ofan improved-construction particularly ada ted .forsecuring round bands on tanks, k'ns lor wherever such bands can befadvantageously'employed.

The invention consists vin certain Vnovel .features in construction andarrangement as `morefully and particularly setforth hereinafter. c

Referring to the accomp anying drawings :T-Figu-re l, is a perspectiveviewshowing the lug in o erativeposition connecting round `band en s.Fig. 2, is a longitudinal section `of the lug showing the Vband endstherein. Fig. 3 is a cross section on the line ii-J3, Fig. `2. Fig. 4,is a bottom plan of the glhe lug shown ,is particularlyadapted for usein adjustably Vcou ling together the oposite ends of round. ands, havingone end Yongitudinally screw threaded to receive a tightening nut, andthe opposite end formed with yan enlarged head.

In the drawings, 1, is the threaded end of the band, having thetightening nut2, thereon, and 3, is the head or enlargement on the oposite Aend of the band. The means empoyed for .tightening or v`couplingtogether the hand ends .are commercially known as lugs or tank lugs. Y

The tank lug of this invention consists 'of a vsingle hollow metal frameformed in any suitable manner, referably by casting, vand the lug ispreferab y so nformed that-,it can be cast without employing a core. Thelugis longitudinally ;r10egated, -arpfodmetely @b1 y.lsongin'fShape,fand'is fopen at :the inner side or hottom, ysaid open bottom beingsurrounded by thefloop-likeor `surrounding Hat bearing :edge A4adaptedto rest Eonl the surface ofthe .tank or other structure -vorobject on which 'the band is secured.

The lug is ,formed hollow with end openings to provide a longitudinalpassage therethrough for the band lends. The intermediate portion ofkthe lug is formed with one ori-more upward or outward arches, theopposite ends of the lug projecting beyond said arch or arches. Oneelongated arch can be employed with or without an `intermediatetopopeningf, if so desired, one end of the arch eing elevated, or Vtwoarches can be employed ,having their u per ends separated by saidopening 5. Ta ing the latter eX- planation of the formation; `6, is anupward or outward arc-h lbetween the side walls 7, of the lugandlocate'd adjacent to the rear end of the lug, the lug being 4openbelow said arch 6.. 1

VAAt the rear end .of the lug, that is, the end ,adjacent to narch, theside walls are conn ected bythe end bridgeor cross connection 8., havinga concaved top face which, in connection with the side walls 7, taperingdown to said crossconnection, `forms a seat for the band :end ,1. This.end 1, passes over the bridge 8 and under arch 6, and is by said arch,held down in the s eat formed by said bridge ybetween .the two .side`guide or stop walls. The bridge 8 `is also braced and strengthened bysaidside walls extending betweenthesame and the arch 6. At the oppositerend portion of the lug, I provide the ,large or elevated arch 9, thelug being open below said arch. This arch is formed with Aoppositevlongitudinal or upright inwardly projecting ,lianges 10, yforming thenut bear- .ing face 11, at the front `side of the arch, said faceusually inclining upwardly and rearwardly.. Within the arch said flangesform asocket or opposite shoulders, behind which `theheaded end of theband engages. The lug extends forwardly from the arch 9, and is formedwith the front kbrid e or cross connection 12, having a concave 'topseat or face,

yand the side walls of the lug taper from the arch 9., down and mergeinto said bridge and vin connection therewith form a seat and sideguides for the end of 'the :band provided with thehead. Said sidewallsbetween the arch 9, and bridge 12, also brace said parts and distributethe strain, while the side walls between the two arches 6 and 9, alsoserve to brace the arches and distribute the strain.

i the lower portion of the arch 9, with the band extendin forwardlythrough the lower portion of t e arch and across the front end bridge12, and between the front ends of the sidewalls. If so desired, theinternal stop shoulders for the head 3, and formed by said flanges 10,can be inclined forwardly and downwardly, so that forward pull or strainon the band will cause said head 3, to draw down and hence hold saidband firmly down in the seat formed by bridge 12.

The band having been passed around the tank or other structure,itsthreaded end is then ilassed longitudinally into the lug throug therear end thereof, that is the band is passed over the rear end bridgeand under the rear end arch and through the upper portion of the frontelevated arch 9, above the opposite end of the band and its head. Thethreaded end of the band passes through the lug at an upwardinclination, and the nut is then applied to the forwardly projecting endthereof and screwed down into engagement with the front face of saidarch 9, to tighten the band to the extent desired.

It will be observed that the pressure of the nut is rearwardly againstthe arch, while the pressure of the head 3, is forwardly against thearch, whereby the strain on the lug is practically equalized. rlhis is afeature and advantage of material importance, particularly in view ofthe fact that the ends of the band practically lap one over the otherand have their bearing abutments against the lug in practically the sameplane extending transversely of the lug. Advantages are also attained byforming the lug with the end extensions constituting concaved seats forthe band with side stop or guide walls thereby holding the lug true orin the longitudinal line of the band and against twisting or lateraldeflection. The formation of the lug is such that it is properly helddown and tightly to the surface of the structure to which the band issecured and against rocking or tilting outwardly therefrom, andfurthermore said lug can be very economically produced of maximumstrength and minimum lightness.

It is evident that various changes and modifications might be resortedto without departing from the spirit and scope of my invention, hence ldo not wish to limit myself to the exact structure shown.

What l claim is z* 1. A tank lug having longitudinal side walls,depressed cross bridges between the opposite ends ofsaid walls, anoutward arch between said walls and adjacent to one end of the lug, andanother outward arch adjacent to the opposite end of the lug andconnecting said side walls and having opposite bearing faces to formopposing abutments for fastening means of opposite band ends, said lugbeing open at the bottom between said side walls and the end depressedbridges, and being open at the top except at said arches, substantiallyas described.

2. A tank lug at both ends having depressed cross bridges forming endconcaved seats for opposite band ends passing in opposite directionslongitudinally of the lug, an outward arch adjacent to one end of thelug and under which one band end passes, an elongated arch through whichboth b and end s are adapted to pass one over the other and havingopposite bearing faces to form opposing abutments for the fastening headand nut of said band ends, respectively, and opposite longitudinalvertical side walls connecting and bracing said arches and end bridgesand extending throughout the length of the lug.

3. A tank lug consisting of an elongated hollow body at both ends havingside walls and depressed cross bridges over which the band ends areadapted to pass between said side walls, whereby the lug is held in thelongitudinal line of the band, said lug between said ends being formedwith an outwardly projecting arch through which the opposite band endspass one over the other, said arch having an inner abutment to receivethe head on one band end and an outer abutment to receive a nut on theother band end, said arch being closed at the outer end and open at itsinner end through the bottom of the lug.

A tank lug consisting of an elongated hollow body open at its innerside and having longitudinal side walls and depressed end cross bridgesat both ends of the lug, and alined intermediate outward arches betweensaid side walls, said lug being open outwardly above said bridges andopen inwardly below said arches, one arch adapted to receive and holddown one band end, and the other through its opening adapted to receiveboth band ends and formed with opposing abutments for the heads on theband ends.
